First off - this is a nice compilation with a great focal point where the tree meets the light area of the sand. However, I would definitely say that the tree is photoshopped in. People should be able to recognize this by looking a bit more critically at the photo. Compare the size of the tree to the size of the grasses. That should tell you that if this was a real "capture", then the tree is approximately 4-6 inches tall at the most. I don't know of any tree in the desert that looks like that and is so small.
